This Working Paper is a compilation of the findings from five separate projects—conducted between 2012 and 2017—that examined approaches to improving the quality of MEPS Medical Provider Component (MPC) data. Each project was undertaken to identify and assess areas to improve data collection strategies and to ensure efficiencies. The primary focus was to address ways to quickly identify separately billing doctors (SBD) in the MPC. These efforts were intended to increase accuracy and reduce resources needed during the process of identifying eligible SBDs with a view to ensure quality and timeliness in the data.
